Patented Sept. 9, 1930 UNITED STATES CHARLES H. KRAFT, OF KANSASCITY, MISSOURI DOOR SUPPORTING AND ADJUSTING MEANS Application filed May 4, 1929. Serial No. 360,492.

My invention relates to adjustable sup- .porting means for doors and while it may be used to advantage with various kinds of doors it is especially useful for supporting e the doors of classroom wardrobes of the character shown by my U. S. Letters Patent No. 1,636,236 issued July 23, 1927.

In order that the invention may be fully understood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is a front elevation of a wardrobe equipped with the invention.

Fig. 2 is a broken horizontal section on line 2-2 of'Fig. 1. Fig. 8 is a'front elevation partly in section of the parts disclosed by Fig. 2.

F.F ig. 4 is a vertical section on line 4 4 of 2 designates the wardrobe which may be constructed in accordance with the one disclosed by my U. S. Patent hereinbefore referred to, or any other suitable type of wardrobe in which the doors 4 are arranged to swing ,outwardly in pairs.

Referring now more particularly to the parts constituting the present invention, 6 designates the legs for supporting all but the two endmost doors 4. As shown by Figs. 1 to 3, inclusive, each leg supports two doors instead of one leg supporting each door as in the patent referred to.

In constructing each leg I provide a post V8 arranged in alinement with the adjacent edges of the two nearest doors-4 and project- 35 ing vertically from a base 10 which may be secured to the floor A by suitable means such as screws 12. The upper portion of the post 8- is threaded as indicated at 14 into the internally threaded bore 15 of a member 16, so that the latter may be vertically adjusted for the purpose of simultaneously raising or lowering the two doors 4 support-ed by the le gr:lhe member 16 has a pair of lateral extensions 20, each of which has a countersunk ball bearing 24 including a nut 26 adapted to rotate upon the balls 28. The nuts 26 are threaded upon axial screws 30 depending from brackets 32, which are secured by suitable means such as screws 34 to the two ass-ociate doors 4.l The brackets 32 are preferably of` i rightangular formation as shown by Fig. 4,

each consisting of a vertical flange 36 secured to the rear side of the associate door with the screws 34, and a horizontal flange 38 extendy ing forwardly beneath the door and provided at its forward portion with the depending screw 80, the lower end of which enters a recess 40 formed in the underlying lateral extension 2O as shown by Figs. 3 and 4, -So

The member 16 of the leg is 'provided at its front upper portion with a horizontally disposed stop 42 against which the adjacent lower portions of the associate doors contact when closed and are thereby prevented from'swinginginto the wardrobe too far and causing the blackboards B to get outof alinement.`

The upper portion of the wardrobe 2 is provided with stops 44, each of which is so lo- 70 cated as to cooperate with the stop 42 in checking the inward movement of the adjacent doors 4 when thek latter are closed. The upper portions of the doors are mounted on pivot-S46 which are arranged in vertical 7 5 alinement with the respective screws 30.

The legs 6a of the two endmost doors are similar to the legs 6, excepting that one of the extensions 20 with its ball bearing 24 is omitted.

From the foregoing description it is apparent that when installingthe door 4, simultaneous vertical adjustment thereof may be had by rotating the posts 8 to adjust the members 16 up or down, while individual ads justments to keep the top and bottom edges of the doors in horizontal alignment are had by rotating either of the nuts 26 to adjust the respective screws 30 up or down. After 90 the nuts 26 have been adjusted as stated they are secured from accidental rotation with set screws 50 threaded in the members 16. By providing one leg for two doors instead of a separate leg for each door as heretofore, economy is obtained in the cost of production and installation and less trouble is experienced in keeping the doors in alinement which is important, because the blackboards B present an irregular and unsightly appear- Y said post and provided with lateral extenance when one is higher or lower than its j companion.' Y

From the foregoing description it is apparent that I have provided supporting means for wardrobes embodying the advantages above pointed out, and while I have shownone form of the inventionv I reserve all rights to such other forms and modifications thereof as properly fall within the spirit and scope of the invention as claimed.

Having thus described f my invention,

what I claim and desire Patent, is:

1. In combination with two doors; a single leg consisting of a post arranged beneath and to secure by Letters lin alinement with the adjacent edges of said doors; a member vertically adjustable upon said post and provided with lateral extensions projecting beneath the doors; and c0- operating means on the doors and said lateral extensions, upon which the :doors are operably mounted. l i v 2. .In combinationwithtwo doors, asingle v'leg consisting of a post arranged beneath and in alinement with the` adjacent edges of said doors; a member vertically adjustable upon said post and provided with lateral extensions projecting rbeneath the doors; axial members depending from the doors, and antifrictional means associated with said vaxial members and the lateral extension.

3; In combination with two doors; a single yleg consisting of a post arranged beneath and in alinement with the adjacent edges of said doors; a member vertically adjustable upon v sions projecting beneath the doors; axial members depending romsaid doors, `nuts threaded upon said axial members, and balls supported bythe lateral extensions and upon which said nuts are adapted to rotate.

In testimony whereof I aiiix my signature. CHARLES H- KRAFT.
